PATENT OF NEV YORK, N. Y.

HOT-AIR REGISTER AND VE-NTILATOR.

SPECIFICATION forming part of Letters Patent No. 623,343, dated April 18, 1899.

Application filed April 18, 1893. Serial No. 677,921. (No model.)

To all whom t may concern:

Be it known that I, IVILLARD S. TUTTLE, a citizen of the United States of America, and a resident of New York, (Brooklym) county of Kings, and State of New York, have invented certain new and useful Improvements in IIot-AirRegisters and Ventilators,of which the following is a specification.

Myinvention relates to that type of hot-air registers in which pivoted fans are actuated to open or close the register-aperture.

- My invention consists in the mechanical movement for operating the fans; also, in the means for connecting the register to the llue; also, in the various other combinations and instrumentalities hereinafter described, and more particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a face view of the register. Fig. 2 is a transverse section on the line 2 2 of Fig. l, taken in the direction of the arrow, as shown. Fig. 3 is a transverse section on the line 3 3 of Fig. 1, taken in the direction of the arrow. Fig. a is a partial longitudinal section on the line fl i of Fig. 1, taken in the direction of the arrow. Fig. 5 is a partial transverse section taken on the line 5 5 of Fig. 1 and especially showing a means of fastening the register proper to the iiue. Fig. 6 is a perspective view, looking into the box or frame of the register, showing the parts in the position they assu me when the fans are closed. Fig. 7 is a similar view with the fans open. Fig. S shows separately the outer sliding bar of the fanoperating device in side elevation. Fig. I0 is a similar view of said bar, taken from the opposite side to that shown in Fig. S. Fig. 9 is a plan view of that bar, taken from below. Fig. 11 is a side elevation of the inner bar of the operating device. Fig. l2 is a side elevation of the same bar, taken on the opposite side from that shown in Fig. 11. Fig. 13'is an enlarged detail view of the bars of the fanoperating device, showing the direction of motion of the parts and their relative positions when the fan is closed. Fig. 15 is a similar view of the fan open. Figs. 14. and 16 are sectional views, respectively, of Figs. 13 and l5, taken on the line ma, which passes through both figures.

Similar numbers of reference indicate like parts.

The form of register to which'my'invention is here shown applied is that of the general type, which has a grating, as 3, Fig. 1, provided with a supporting frame or boX 9. Hitherto such registers have been provided with pivoted fans or slats and with means for operating such fans to open or close the aperture in the frame. Ordinarily these fans are made of cast metal, with integral pivots projecting from their ends and located about midway the width of the fan. These pivots usually enter openings in the frame. In my device the construction of the fan is radically different. Thus, referring to the fan 10, Fig. 3, itwill be seen that this fan is made of thin sheet met-al, but is given requisite stiiness by a liange 11, turned over at its transverse edge. At one longitudinal edge of the fan the metal is also rolled over to produce a sleeve or tube 12. The fan-pivot 13, which is a rod of wire, passes through'an opening in the wall 14, Fig. 4, of the frame, then through the tube 12, then through the slotted sliding tube 17 of the operating device, as will hereinafter be eX- plained, and then is received in an opening in the opposite wall of the frame. The upper end of the pivot 13 may be turned over or headed. The fan 10 (and this is true of the other fans) turns freely upon vthe Xed pivot-rod 13.

The location of the pivot-centers of the fans near to the grating allows ofthe use of a shallow frame or box 9, because, as is obvious, no.

part of the fan comes between the pivot-center and the grating when the fans are in their open position, as clearly.- shown in Fig. 3. When the fans are closed, as shown in dotted lines, Fig. 2, they lie wholly within the frame. This is also well illustrated in Figs. 6 and 7.

The arrangement which I here show of a pivot-rod 13 passing down through the tube 12 and extending along the whole longitudinal edge of the fan is a preferable arrangement andnot one to which I limit myself, because, as is obvious, instead of usinga single pivotrod, passing, as stated, through the openings in the opposite walls of the frame and through the tube, I may employ two pivot-rods, one at each end, entering for a certain distance into the tube. sary for the tube to extend over the entire length of the frame. These are immaterial IOO In that case it will not be necesfrom the lower edge of the fan parallel to the fan pivot-rod. The principal features of this mechanical motion are the trough-shaped slotted bar of sheet metal 17,( shown in Figs. 8, 9, and 10,) the link 19, which is shown best in Figs. 8 and 14 and is pivoted at 2O within and to one side of the trough-shaped bar 17, and a pivoted fan having the projecting studpin 16, to which piu the free end of the link 19 is coupled.

Particular attention may here be called to the fact, as best shown in Fig. 14, that the width of the link 19 is less than the distance between the sides of the trough-shaped bar 17, so that when the bar 18 (the function of which is to couple the pins 16 of the several fans together, so that all the fans will operate at the same time) is inserted into the troughshaped bar 17 one side of the bar 18 comes between the outer edge of the link and the wall of the bar 17. This is very clearly shown in Fig. lat and also in the perspective views Figs. 6 and 7, which, moreover, exhibit the fact that the bars 17 and 18 lie within the box 9 and against one wall'thereof.

Returning now to Figs. 8, 9, and 10, in one side of the bar 17 there is a right-angled slot 2l, having a curved edge 22. In the other edge there is a straight longitudinal slot 23. Bar 18, as showniu Figs. 11 and 12, is flanged over at its top at 2t. On one of its sidesand at the upper portion the metal is entirely cut away, as noted at 25, and other openings, as 26 27, are also in this side. In the ange 2J: and in the opposite side of the bar are notches, as 28 and 29, and adjacent to each notch is a hole 30 31 Now, considering the parts in the position they assu me when the fans are closed,as shown in Figs. 6 and 13, the pivot-wire 13 after passing through the tube orrolled-over portion 12 on the edge of the fan first passes through the slot 2l of the sliding bar 17 and then through a notch 29 on bar 18, and nally is received in its bearing in the frame 9, while the studpin 16 of the same fan also passes through the slot 21 in the bar 17, and then passes through the hole in the free end of the pivoted link 19, and then enters the hole 3l in bar 18. It will be understood, therefore, that the Wire 13, about which the fan turns, is fixed in position, because it has bearings in the walls of the box 9. The stud-pin 16, however, on the fan obviously describes thel arc of a circle around the pivot-wire 13 as the fan is opened or closed.

Referring now to Figs. 13, 14, 15, and 16, the operation of the foregoing device will be readily followed. In Fig. 13 the fan 10 is in position to close the register-opening. The bar 18 lies wholly within the bar 17. The link 19, as here shown, stands in vertical position. The stud-pin 16 is in the horizontal part of the slot 21. Now let it be assumed that the outer bar 17 is moved to the left or in the direction of the arrow 33 of Fig. 13. Inasm uch as one end of the link 19 is coupled to that outer bar, the coupling-pivot 2O is also carried to the left, as shown by the small arrow (marked 33X) in Fig. 13. As this pivot 2O is carried to the left obviously the link itself in changing position pulls upon the stud-pin 16, and thus both uponthe fan and upon the inner bar 18, to which that pin is connected; but as' the pin 16 can only describe the arc of a circle around the pivot-rod 13, as indicated by the arrow 3l, it is obvious that the fan 10 must swing into the position represented i'n Fig. 15-that is to say, the open position. Because the pin 16 is connected to the inner bar 18 that bar is moved outwardly from its seat in the bar 17 in the direction of the arrow 35 in Fig. 15, so that theparts then assume the position represented in Fig. 15, the link 19 finally standing at right angles to its original position, as shown in Fig. 13. The pin 16 will then have traversed the rectangular slot 21, or rather the rectangular slot 21 will have moved over the pin 16, so that the ultimate position of the pin 16 will be as represented in Fig. 15. At the same time the bar 18 in addition to moving in the direction of the arrow 35 wi ll also have been carried in the direction of the arrow 36,'or,'in other words, its actual motion will be a resultantof the two motions indicated by the arrows 35 and 36. In order to restore the parts to their normal position, or, in other words, close the fan, the bar 17 is moved to the rightof Fig. 15,the parts operating in the reverse manner, while the curved surface 22 of the slot 2l bears against the pin 16 and acts as a cam to assist in swinging the pin 16 to the right to draw bar 18 back inward to its original position inside the bar 17.

lt will be observed that the position. of the link is always at right angles to the plane of the fan, so that the-link acts upon the fan' in the most direct manner.

Recurring now to Figs. 6 and 7, it will be seen that I there show three fans lO, 37, and 38. The arrangement of the fans 10 and 37 is the same-that is to say, both of these fans are connected by their pins 16 to the links and inner and outer bars 17 and 18 in the manner already described. The fan 38, however, does not require this mode of attachment. Its pivot-rod 39 is directly journaled in the frame 9, while its pin 40, answering to IIO ' tened together, as is usual.

pin 16 of fan 10, is simply journaled in the bar 18. Of course it will be obvious that when the bar 1S takes the position shown in Fig. 7 through the operation of the rest of the device, as already described, the pin 40 will have moved into such position as to cause the fan 38 to swing on its pivot 39 and so stand open or parallel to the other fans 10 and 37.

The spring 41 (shown in Figs. 1 and 2) bears upon the upper surface of the bar 17 and serves as a friction device to hold the fans in adjusted position.

In Fig. 5 is shown a device for connecting the register to the flue in which the registerbox 9 is inserted. Around the flange of the grating S are made apertures, in which vare inserted screw-bolts 42. These receive nuts 43, which when the screws are set up bear tightly against the flue H14 and so clamp the same against the register-box 9. The screws are prevented from being further inclined by reason of their bearing upon lugs 45, integrally formed with the grating S. It will also be observed that the grating S and frame or box 9 are made integral and are not formed in separate pieces bolted or otherwise fas- The mode of connection described in the preceding paragraph is expressly suited to the uniting of such an integrally-constructed register with the flue.

On reference to Fig. 13 it will be seen that the fan 10 when in its closed position, as there shown, is locked in place, because the pin 1G then bears upon the horizontal edge of the slot 21, and hence the fan cannot be put in open position either by the hand directly acting upon it or by any chance draft sweeping inward the register through the grating. In order to move the fan from its locked position, it is necessary to carry the outer bar 17 to the left in the manner which has already been described.

By the term box or frame herein I mean a frame adapted to receive and support the fans or valves. The term quadrangular face of the box or frame means the quadrangle formed by the edges of the walls of said box orframe on either side. The term register opening or aperture7 means the space inclosed within the walls of the frame or box.

I claim- 1. rIlhe combination of a register-frame, a Hue receiving the same, a headed and threaded bolt passing through an opening in said frame, anda nut on said bolt bearing laterally against said flue; the said nut and bolt I operating to secure said register-frame to said ue, substantially as described.

The combination of a pivoted fan and support therefor, a slotted slidingbar through which the fan-pivot passes, a stud-pin on the edge of said fan parallel to said pivot and a link coupled at its ends respectively to said sliding bar and said pin, and operating to swing said fan inone direction or the other according as said bar is moved one Way or the other, substantially as described.

3. The combination with the frame and a fan having a pivot-rod therein vof a slotted sliding bar receivingsaid rod, a link'coupled at one extremity to a pin projecting from the end of the fan parallel with the pivot-rod, and coupled at the other extremity to said sliding bar; the saidl link operating to swing the fan open or shut according as said bar is moved one way or the other, substantiallyas described.

4. The combination with the frame and two or more fans pivoted therein at the extremities of the longitudinal edges of al slotted sliding bar receiving the pivot-rods of said fans, and a series of links coupled to said bar at one end and respectively coupled at their other ends to pins on said fans whereby when said bar is moved in one or the other direction said fans are swung on their pivots, substantially as described. Y 5.
